Truth has a variety of meanings, primarily being in accord with fact or reality, fidelity to an original or to a standard or ideal and, in common usage, constancy or sincerity in action or character. The opposite of truth is falsehood, which, correspondingly, can also take on a logical, factual or ethical meaning.
Language and words are a means by which humans convey information to one another. As such, "truth" must have a beneficial use to be retained within language. Defining this potency and applicability can be looked upon as "criteria", and the method used to recognize a "truth" is termed a criterion of truth. Since there is no single accepted criterion, they can all be considered "theories".[clarification needed]
In religious context, truth is regarded as an aspect of God since the deity is reputed to have knowledge of all things (omniscience). Thus God may hold the office of divine judgment, by which all people are ultimately judged.
Various theories and views of truth continue to be debated among scholars and philosophers. There are differing claims on such questions as what constitutes truth: what things are truthbearers capable of being true or false; how to define and identify truth; the roles that revealed and acquired knowledge play; and whether truth is subjective or objective, relative or absolute.
Data ( /ˈdeɪtə/ DAY-tə, /ˈdætə/ DA-tə, or /ˈdɑːtə/ DAH-tə) are values of qualitative or quantitative variables, belonging to a set of items. Data in computing (or data processing) are often represented by a combination of items organized in rows and multiple variables organized in columns. Data are typically the results of measurements and can be visualised using graphs or images. Data as an abstract concept can be viewed as the lowest level of abstraction from which information and then knowledge are derived. Raw data, i.e., unprocessed data, refers to a collection of numbers, characters and is a relative term; data processing commonly occurs by stages, and the "processed data" from one stage may be considered the "raw data" of the next. Field data refers to raw data collected in an uncontrolled in situ environment. Experimental data refers to data generated within the context of a scientific investigation by observation and recording.
The word data is the plural of datum, neuter past participle of the Latin dare, "to give", hence "something given". In discussions of problems in geometry, mathematics, engineering, and so on, the terms givens and data are used interchangeably. Such usage is the origin of data as a concept in computer science or data processing: data are numbers, words, images, etc., accepted as they stand.
